Hi guys, I need a replacement power supply for an ancient LaCie external hard drive. It's a 2TB QUADRA. The P/S is a big black wall-wart that puts out 12volts @ 3amps into a barrel plug. I have a photo of the HDD to help with identification. LaCie/Seagate have no clue because it's about 20 years old. If you have any intel, I'd appreciate you hitting me up here. Many thanks! Nigel.
